UK police have appealed to the press not to jeopardise a forthcoming public appeal on the disappearance of Madeleine McCann.
Reports suggest a new picture of a possible suspect connected to the investigation is to be released as part of the initiative.
British detectives investigating Madeleine's disappearance are believed to be issuing an "e-fit", but Scotland Yard would neither confirm nor deny the claim.
In a statement, the Metropolitan Police said: "We are not prepared to discuss, comment or speculate on the content of the upcoming appeal in relation to the investigation into the disappearance of Madeleine McCann.
"This has been weeks in the planning and each element of the investigation must be set into the overall context of the appeal.
"We will be asking for help from the public in a number of countries, delivered through a series of public appeals.
"We will do nothing to jeopardise the effectiveness of these appeals and we have repeatedly stated that media speculation can be damaging to our efforts.
"The MPS will release the relevant material at the relevant time."
